Adjust MyFlavor 40K Review: Flavor Mixing, Specs and Is It Worth It in 2026?

Originally published March 12, 2025 · Updated October 2026 · By the VapeOwls Team

Quick answer: The Adjust MyFlavor 40K is a dual-flavor disposable that lets you blend two flavors at three levels (A<B, A=B, A>B). It has a 20 mL tank, an 800 mAh USB-C battery, dual mesh coils and 5% nicotine, rated for 40,000 puffs in Normal Mode or about 20,000 in Burst Mode. The concept is fun and the price is now low ($9.99 on sale, about $0.25 per 1,000 puffs), but hands-on reviews found the flavor muted in Normal Mode. It is best for vapers who like mixing and value.

How Flavor Mixing Works

Each device holds two flavors in a dual tank. A button cycles through three blend levels:

• A < B: mostly flavor B with a hint of A.
• A = B: an even blend.
• A > B: mostly flavor A with a touch of B.

The screen shows battery, e-liquid and the current blend, and a separate button switches between Normal and Burst Mode. The device is draw-activated, so there is nothing else to set up.

Normal vs Burst Mode

Normal Mode is the efficient setting behind the 40,000-puff rating. Burst Mode runs hotter for denser vapor and a stronger hit, and the rating drops to about 20,000 puffs. Hands-on testing by Vaping360 found the airflow loose in Normal Mode, which thinned the flavor, while Burst Mode felt warmer and fuller.

Best Flavors to Try

We list 13 flavors, including:

• Orange Strawberry – the reviewers’ standout pairing, though orange tends to lead at every setting.
• Strawberry Banana and Watermelon Mango Peach – easy fruit blends.
• Blue Razz Ice and Midnight Ice Chill – for cooler hits.
• Mixed Mint – peppermint with Miami mint.
• Tangerine White Gummy, Watermelon B Pop, Triple Berry Grape and more.

See live stock on the MyFlavor product page.

Tips for Better Flavor

• Try Burst Mode first. The warmer setting gives a fuller taste, which matters most on the lighter fruit pairs.
• Start at the even blend. Taste both flavors at A = B, then move one step toward the flavor you want more of.
• Take slower draws. A longer, gentler pull usually brings out more flavor than short, sharp puffs.
• Keep it out of the heat. Leaving any disposable in a hot car can change the taste and drain the battery.

If you still want a bolder hit, pick a pairing with a stronger lead flavor, such as Orange Strawberry, rather than a mild mint or berry mix.

Battery and Charging

The 800 mAh battery typically lasts about a day of regular use. Charging over USB-C is slow, around 95 minutes in the published review, but pass-through charging lets you keep vaping while it charges.

Pros and Cons

Pros

• Fun, easy flavor mixing with three levels.
• Large 20 mL tank and 40,000 rated puffs.
• Very low cost per puff at the current sale price.
• Draw-activated and simple to use.

Cons

• Flavor can taste muted in Normal Mode.
• No adjustable airflow.
• Slow charging.
• Some pairings blend less evenly than the settings suggest.

MyFlavor vs MyCool and MySweet

The brand makes three devices with different tricks: the MyFlavor mixes two flavors, the MyCool adjusts the cooling level, and the MySweet adjusts sweetness. If you cannot decide, the three-device bundle gets one of each for $25.99. Browse every model on the Adjust brand page.

Is the Adjust MyFlavor 40K Worth It?

At full price, the muted flavor was hard to recommend. At $9.99 it is a different deal: about a quarter of a cent per puff for a 40,000-puff device you can tune yourself. Buy it if you enjoy experimenting with blends and want value; skip it if you want the boldest single flavor or adjustable airflow. Value hunters should also check our cost per 1,000 puffs ranking.
